Preheat oven to 375°F. Spray an 8”x4” loaf pan with cooking spray. Line it with parchment paper.
In the bowl of a stand mixer, add the eggs, oil, and heavy cream. Mix on medium speed for 1-2 minutes, until light and fluffy. Scrape down the sides of the bowl.
In a large bowl, whisk together the coconut flour, flaxseed, sugar, baking powder, xanthan gum, salt, and cinnamon. Mix well, then add to the bowl of the stand mixer. Mix again for 1–2 minutes or until fully incorporated. The batter will be thick.
Pour the batter into the prepared pan. Bake for about 45 minutes or until a toothpick inserted into the middle of the bread comes out clean.
Let the bread cool in the pan for 15 minutes.
Remove to a wire rack to cool completely.
Notes
Use an 8" x 4" size baking pan for best results.
The batter will be thick, more like thick cake batter.
Let the bread cool before turning it out from the pan onto a wire rack.
